Since then I got married, had a child with another one on he way any day now. 

People new to the "terms business" when you are talking to sellers and buyers you are basically being "parent child"; we are the parent of the child. 

I am more worried about the real estate back taxes, IRS back taxes, unpaid utility bills, alimony/child support unpaid, and also the mortgage.Should I run a title search?

Apparently when you pass an annual income of $125K/year certain you no longer get certain deductions like the Child education credit, interest deduction from students loans, and most surprising we cannot deduct anything from the expenses of our rental property.

After some studying on Austin area and biggerpocket's teaching on real estate investment I'm trying to screen some homes in Hutto,TX and Round Rock, TX.The idea of a duplex seems to be the best solution for me and my wife and our new born daughter, but I find duplexes rare in Austin area and often overpriced.

If all goes well you'll be retired by the time your child is 25.Time to get a seat as an "adviser" on the board :)

There should be a clause in your lease saying that only the people signing the lease and children identified by name are authorized to live there and any body else "must have the express written permission from the owner".Obvious exceptions would be birth of new child or adoption/foster care.

The owners are parents buying for their child. 

Hello everyone,I'm 35 years old and married with one child.

I remember as a child my parents bought me a Tandy computer.
